Part Number: TXB0108

Hi Team,

Can we use a TXB0108  level translator with external pull-up resistors for the I2C interface.

Thanks,

    Hi Shifali,

    No. TXB is suitable for push-pull and not for open-drain applications such as I2C.

    Please see below as I would further recommend the TXS family (TXS0108E for example) with internal pull-ups and the LSF family (LSF0108 for example) where you can use external pull-ups, thanks.

    Best Regards,

    Michael.
